NECK YOKE.

Application filed August 5, 1927. Serial'N'o. 210,882.

This invention relates toneck yokes, and particularly to a type of neck yoke used in association with a wagon neck yoke and, in practice,neck yokes ofthis type .are known as breast'yokes or twin yokes, by reason of the fact that two short yokes are employed, one at each end ofthe large so-called wagon neck yoke.

It is an object of this invention to provide a neck yoke of the character identified in association'with a novel hitch or connection by which the neck yoke can be detachably applied to the wagon neck yoke, and whereby the means of connecting the yokes maybe removably installed as a part of the said neck yoke. p

The invention is an improvement on that type of neck yoke disclosed in applicants Patent No. 1,07 7,645, dated November 4, 1913, and the present invention has for an object the production of a neck yoke which is durable and in which the hook of the central collar of the neck yoke maybe removably applied. The said hook undergoes the greatest amount of wear and is the part that becomes impaired through use, so that the provision made for its substitution is one of the features of the invention.

It is a further object, however, of this invention to provide novel means whereby strain on a bolt by which the hook is attached to the collar is imparted to the said bolt approximately longitudinally of said bolt, rather than transversely thereof. On account of the foregoing, the durability of the bolt is increased, and the cost of maintaining the breast yoke in an eflicient condition is minimized, as compared with the cost of upkeep of breast okes of other types.

A still further object of. the invention is to provide a novel. joint between the collar and the shank of the hook and between the inner end of the shank of the hook and the neck yoke.

It is furthermore an object of this invention to provide a novel ferrule, or what may be termed a semi-ferrule and ring, whose configuration results in simplification in its production or manufacture, since it can be cast of malleable iron without the employment of a core in the mold. The said ferrule cannot become displaced due to changes in the condition of the yoke or due to its shrinkage.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination of parts to b e hereinafter more fully set forth and claimed; j

y In. describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote'correspondingparts in the several views, and in which Figure lillustrates a view in elevation of a neck yoke embodying the invention;

Figure 2 illustrates a View in elevation of the removable hook Figure 3 illustrates a sectional view on the line 33 of Fig. 1; and I Figure 4 illustrates a detail view of one of the ferrules. V

In these drawings 5 denotes an ordinary type of neck yoke having a central collar 6 which may be secured thereon by afastening 7, such as a screw or the like. The collar has a recessed boss 8 and a latch 9 coacts therewith and occupies a space between a the said boss and the end of the billlO of the hook 11. The inner end of the shank 12 of the hook is flared, as at 13, and a wedgelike body is thereby produced, whose end surfacel f is concave or shaped to conform to the external surface'of the yoke.

Extensions 15 and 16 of the collar converge and conform to the contour of the side surfaces of the shank of the hook which said extensions embrace. The side extensions 15 and 16 are provided with apertures 17 and 18, in the formation of which, the material of the side extensions is shaped to form an: nular flanges, such as 19, and an aperture 20 through the hook is enlarged at the sides of the shank to receive the said annular flanges. A bolt 21 extends through the ex tensions of the collar and through the aperof the bolt, whereas there is no transverse or a lateral strain on the said bolt, since the wedging action on the inner end of the shank of the bolt will cause the strain on the bolt to be longitudinally thereof, as stated.

The ferrules 22 and 23 are constructedalike, except that-the ferrule 23 has an eye or seat 24 which constitutes an anchorage for the end 25 of the latch 9.

Each of the ferrules, except as to this anchorztge, consists oi a curved body, which curve conforms to the contour of the yoke, and each ferrule may be secured in place by a fastening 26, such as a rivet, extending through the yoke and through the ferrule. An eye 27 is formed as a part of each ferrule, and as the body of the ferrule constitutes a curved plate With an eye integral therewith, the same can be cast, as stated, without the employment of a core.

We claim:

1. A neck yoke having a collar with converging extensions, the said extensions being apertured and provided with annular flanges at the apertures, a hook having a Wedge-shaped shank tittedbetween the extensions and anaperture in alineinent With the apertures of the extensions, the said aperture being enlarged at the sides of the shank to form channels for the reception of the annular flanges, and an element extending through the aforesaid apertures for coi1nect- 1ng the shank of the hook to the said extentensions.
